*SPRING 2024 - WHAT NOW?*

For
grades and office hours, see my Outlook email or email me at kkuniyuk@sdccd.edu ; apparently, email for
the class Canvas site goes down after the end of the semester (Sat., May 25)!

*CALENDAR / *

*YOUTUBE VIDEO PLAYLISTS (optional)*

*WiFi**, EMAIL, STUDENT RESOURCES, CAMPUS
EVENTS*

*GOING ONLINE!*

**CANVAS: Discussion
Boards and NetTutor!**

I don’t do
much with Canvas, but a student discussion board and a NetTutor
link are there.

**Notes on using the Canvas site: **

*ALEKS Extra Credit*

*Printing Suggestions for Typed Files*

I recommend two-page-to-a-side and/or double-sided printing to
save paper. Color printing is nice, but B&W printing is cheaper.

These
are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is
compatible with your system!

*Class Notes*

Many
students benefit from **printing the notes** for a lecture beforehand, **reviewing**
them, and **commenting** on them in class.

You
may want to take personalized sketch notes in class.

Corrections: (0:48-1:07) The
double-nappe cone (or simply cone here should not be thought of as finite, so
there are no bases nd there is no base perimeter. The term directrix is used elsewhere,
especially when describing parabolas.

previous semesters, the final was cumulative. For your information, here was
